Device for assembly and electrical connection of modular apparatuses such as circuit breakers or similar
First Claim
1. A circuit breaker device for assembly and electrical connection of a plurality of modular power apparatuses installed on a mounting rail with auxiliary units, said circuit breaker device comprising:
- modular cases adjoined by their lateral sides to form a horizontal row;
power apparatuses residing within said modular cases and being electrically connected and/or supplied with power up-line by a common connecting comb in the form of a bus;
at least one conducting bar extending generally parallel to the longitudinal direction of the rail, and generally perpendicular to the lateral sides of said modular cases and facing said comb;
contact strips of each of said power apparatuses being electrically and selectively connected up-line to at least one conducting bar;
connectors, each connector having a first end electrically connected to a contact strip and a second end for engaging a selected conducting bar, whereby the contact strip of each power apparatus forms an end part housed in a groove provided in a face of the modular case;
said groove being open in the direction of the comb, and said end part and groove extend perpendicularly to the at least one conducting bar over virtually the whole height of the common connecting comb to enable a connector to be connected to a contact strip in several positions along said end part, corresponding to a longitudinal position of at least one conducting bar.

Abstract
The present invention relates to a circuit breaker device for assembly and electrical connection of modular power apparatuses. This device is designed to perform electrical connection of a plurality of power apparatuses, such as circuit breakers, installed together on the same mounting rail with auxiliary units. The set of electrical power apparatuses are electrically connected and/or supplied with power up-line by a connecting comb. This comb is in the form of a bus comprising at least one conducting bar extending generally parallel to the longitudinal direction of the rail and generally perpendicularly to one of the faces of the cases, the bars each being connected to one of the phases or to the neutral. Contact strips of the power apparatuses are electrically and selectively connected up-line to one conducting bar by a connector in the form of double-blades or double-grips, cooperating via one of their ends with the contact strips of the apparatuses and via their opposite ends with the conducting bars.
